magnetic field of a straight wire due to static current
Posted: 12 Dec 2018, 20:24
Dear Elmer-community,
I am facing a problem which is very close related to the test case which can be found here:
https://github.com/ElmerCSC/elmerfem/tr ... teady_wire
In fact, it is the same test except for the fact, that I use a different meshed geometry.
I want to compare the magnetic field with the results of the quasi-static case (E.g. Angular frequency =100rad/s) of the Elmer-GUI Tutorial 7 "Magnetic field induced by harmonic current in a wire".
If I use the provided test case with the wire.grd geometry and a desired current of 188.4 A to get the expected magnetic field of 0.037 T everything works fine.
But If I use my meshed geometry I get an implausible B-Field distribution as depicted in Figure. In the .sif I only changed the boundary conditions.
I have applied the boundary conditions by using Gmsh and using the command:
ElmerGrid 2 4 GmshWire
I do not see any difference compared to the test case "mgdyn_steady_wire".
The sif File as well as the geometry are enclosed in this Post as zipFile. I highly appreciate if someone could help me.
Best regards,
Phlix
